TO ALL WHOM IT MAY CONCERN:

Be it known that I, SAMUEL R. Domenic, ofthe city, county, and State of New York, have invented'a newand improved Packing for Railroad-Oarandother Axles and that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification 'o f'the same, wherein I have set forth the nature and principles of my said improvements, by which my invention may be distinguished from all others of a similar class, together with such parts as I claim and desire to hsvesecured to me by Letters Patent.

The present invention relates more particularly to the packingof railroad car axles, although it may be adapted-to the packing used for other axles.

And the invention consists, y

In applying to the axle a packing, whose periphery is grooved so as to receive a v-shaped lining, which acts as a wedge against the grooved sides of packing, through. the pressure of an elastic encircling-band on said lining, whereby the packing is spread out, as it were, against'the sides of the lubricating-chamber in which the packing is placed, and thus prevent the passage of dust, dirt, &c., to the lubricating-bgur.

In the accompanying plate of drawings, my improvements in packin -Ware illustrated- Figure 1 being a side viewv of the lubricating or journal-box, with its chamber containing the packing, in verti'cal section. I

Figure. 2, a section, taken through the centre of the packing, in a plane parallel with-its'faces or sides.

Figure 3, a tranversc verticai'section, taken in the plane of the lines: 2:.

A, in the drawings, represents a canazrle, and B the chamber of the lubricating or journal box,fin which. the packing C for the axle is placed and confined. This packing C, in the present instance, is made of leather, and in two parts or sections, D and E, which are'joined together by a tongue and groove.

F, a groove around the packing C, and Go sheet-mctal lining to the groovedi', This lining is made of a 'l-shape, so that, as it is pressed into the groove F, it will throw out, as it were, the sides or faces H of the packing against the sides I to the chamber 13, and thereby close the packing about the chamber B to-the passage of dirt, dust, &c., through the saidchamber B to the chamberof the lubricating or journal-box in which the oil or other lubricating-medium is placed.' This lining is made in sectional pieces, corresponding to the divisions of the packing. i

J, a chain, partially encirclin'gthe packing C, with its two ends joined by a spiral or coiled spring, K, by

, means of which the chain is caused to bind' or'press upon the packing with a yielding, elastic, and flexible pressure, confiningit to the axle suificientlyto close the packing to the passage of dust, dirt, 350., throughit,

around the axle, to the lubricating or journal-box of chamber.

In lieu of using a chain, with a springconncction, as above described, a cord, string, wire, or other l may be employed, or a continuous encircling elastic India-rubber band.

i From the above detailed description of my improvements, it is apparent that the many advantages hereinb'et'ore stated are secured, and a packing obtained which is in every respect perfectly closed to the passage of dirt, dust, &c., through both its joints with the axle and with the lubricatingorjournaI-box, to the oil or other ummeting-material within the latter, the importance oi which is obvious. V

, What I claim as my invention, and desire to have secured to me by Letters Patent, isn 1. The v-shaped lining G,-bearing against the grooved paclting G, and supporting the partly-yielding and tron-yielding encircling line J K, substantially as herein represented and described.

2. The combination of the grooved sectional packing C DE, the V-shaped lining G, the encircling-chain J, and its yielding connection ,K, substantially as and forthe purpose described.
